dhcp server stops listening for messages

[isarantis]

Hello sorry for the generic title but my issue is bit strange.
-The goal
In my network i want some clients getting (static like) ip from my dhcp server to leverage network booting, and the rest ( unidentified ) clients to get an ip from my dynamic range. The static bindings are outside of this range driven by a config file that constantly changes (thus the function).
-The config
I have created a dhcp server and im giving addresses with this example config:
{ range: [ 'xxx.xxx.xxx.29', 'xxx.xxx.xxx.30' ], static: [Function: bound ], dns: [ '1.1.1.1', '8.8.8.8' ], netmask: '255.255.255.192', router: [ 'xxx.xxx.xxx.62' ], broadcast: 'xxx.xxx.xxx.63', bootFile: 'sarantis.kpxe', tftpServer: 'xxx.xxx.xxx', server: 'xxx.xxx.xxx.25', randomIP: true }
-The issue
first of all i get alot this error that crashes the server on its first discovery
`projectRoot\node_modules\dhcp\lib\dhcp.js:302
const ip = this._state[oldestMac].address;
^

TypeError: Cannot read property 'address' of undefined`
also i am having an issue that after some time the server stops responding or getting (tested via listeners on 'message') without any error or exception.
I managed to narrow it down that if i give away all the dynamic ips from the range dhcp-server stops working for both dynamic and static-like clients.

If you have any ideas on how i could probably solve this issue i would like to check it out.
Thank in advance.

Update:
Maybe i have managed to narrow down the first issue: it happens when the first discovery is on windows with static-like ip ( 70% sure)
